摘要

During the period 1999-2002 the Woodman Alliance—consisting of Halliburton KBR (KBR), Clough Engineering and Western Australia's Water Corporation—was formed to upgrade and amplify the Woodman Point Wastewater Treatment Plant in Perth, Western Australia. A major component of the project was the design and construction of a new sewage pumping station (Munster Pumping Station No. 3) to be built adjacent to the treatment plant. Instead of the more traditional wet-well/dry-well system, the KBR design team decided to adopt a 'follow-the-flow' system for the new sewage pumping station (Munster Pumping Station No. 3). This system eliminates the need for the traditional wet well and is based upon achieving a smooth transition between the open channel flow in the incoming sewage pipe system and the pressurised flow in the pumped section by closely matching the pumping rate with the incoming flow. However, while 'follow-the-flow' sewage pumping stations can yield significant capital and operational cost savings compared with the more traditional wet-well design, more parameters have to be considered during their hydraulic design, In the case of the Munster Pumping Station, balance was achieved between the storage within the sewerage network and the stability of the surface waves generated by the instantaneous unbalance created between the sewage flow and the pumping rate. A review of the available literature yielded no design standard and only sparse information on the 'follow-the-flow' design. This limited information, however, was used to develop a preliminary design, following which a hydraulic modelling study was carried out. The results of the study were used to refine the preliminary design and to gain an insight into the behaviour of the system under the expected range of flow conditions. Numerical simulations of the control system confirmed the controllability of the pumping station within parameters identified by the model. A cost comparison with the wet-well alternative has confirmed the cost benefits of the follow-the-flow system: capital savings for Munster Pumping Station No. 3 are in the order of 6% and this percentage is expected to rise to around 10% with further refinements in future designs; operating savings are estimated to be in the order of 10% on an NPV basis for this project. The use of physical hydraulic modelling in the design process provided significant benefits in terms of increasing the knowledge of and confidence in the design. During commissioning the pumping station was found to perform in a similar manner to that predicted by the hydraulic model. For future designs, hydraulic modelling would only be required to refine the design for a particular requirement or to increase savings.
